APPARATUS FOR GUIDING FABRICS INTO STENTERING-MACHINES.

To all whom it may concern:

Be it known that we, TnoMAs COOK and GEORGE DURRANT, subjects f the King of Great Britain and Ireland, and residents, respectively, of Staleybridge, in the county of Chester, and Higher Opens'haw, Manchester, in the county of Lancaster,England, have invented certain new and useful Improvements in Apparatus for Guiding Fabrics into Stentering-Maohines, of which the following is a specification.

Our invention relates to improvements in apparatus for guiding fabrics into stentering or like machines and while applicable for use in connection with guiding arrangements in general is particularly adapted for employment in connection with the automatic guiding apparatus forming the subject of an application for patent Serial No. 78%842 filed August 14th 1913 made by George Durrant, one of the present applicants the object of the present invention being to provide preliminary guiding means for the cloth passing into the stentering or like machine and particularly to such types of stentering machine as are provided with what is known as a swissing motion.

Where motions of the type referred to'are employed the cloth, while generally moving forward by being attached to the stenter chains at each side of the machine, is momentarily retarded at one side or selvage and advanced at the other side, alternatively, so causing the weft of the fabricto assume a position varying from a line at right angles to the sides to a line at an inclination thereto. This action is known as swissing and as a result that portion of the fabric which is entering on to the stenter chains is alternatively slack at one side and tight'at the other. To accommodate this action the cloth is usually passed over guide rollers arranged at the front end of the stentering or like machine, such rollers usually being of a conical type so that the tendency of-the selvages of the fabric is to'rise toward the higher parts of the cones and so keep the fabric stretched somewhat transversely. Further j erly take place.

Specification of LettersPatent.

ure 1 a side elevation of so much of a stentering machine as is necessary to show the application of our invention thereto and Fig. 2 plan of same.

In carrying out our invention we mount each conical roller a on a spindle b which is fixed to an arm a. The arm 0 has a socket (Z which is mounted on an arm or bar 6, the ends of which are pivoted to links 7" which project in opposite directions and which are normally arranged parallel to each other. The other ends of the links f are pivoted to a supporting bracket 9, so that the spindle b and the roller a are constrained to oscillate Patented Mar. 23, 1915.

in a straightline. This straight line is ar-r ranged in a suitable position with respect to the cloth under tens1on, and when the tennected to thebracket g and to one of the links V lVith mechanism of the type described it is impossible for the rollers to stick as is sometimes the case when they are mounted on slides. any particular detail construction of link parallel motion solong as the objects we have in view are attained. r

In conjunction with arranging each roller on a parallel motion device we mount it on suitable bearings 2', usually ball bearings, supported by the central spindleb, the inner end of which 1s pivoted to a bracket j fixed on the arm 0 ofthe link motion, such spindle being so arranged that it can be turned about the vertical pivotal center is and then be locked in position at any: suitable angle. The locking may conveniently be elfected by forming an arm m on the spindle b carrying a bolt of passing through a slot 0 in the bracket y'. We do not, however, confine ourselves to this particular detail arrangement as it Will be obvious adjustment can be We do not confine ourselves to readily carried out in other Ways. The roller spindle bracket j is likewise mounted on an arm 0 of the link motion so that the spindle Z) may be raised and lowered at its free end as required to place the cone or roller in any suitable position. As shown in the drawings this adjustment may be effected by a set screw p. By the aforesaid means adjustment of the roller is provided for in all directions required.

In some cases a cylindrical roller may be employed in place of a conical one, the flexibility of the cloth permitting it.

What we claim as our invention and desire to secure by Letters Patent is 1. The combination, with a stationary support, of two links having their opposite ends pivoted to the support and normally arranged parallel to each other, a bar having its ends pivoted to the adjacent ends of .the said links, a spindle mounted on the middle portion of the bar, a roller ournaled on the said spindle, and means for moving the roller in a straight line in one direction.

The combination, with a stationary support, of two links having their opposite ends pivoted to the support and normally arranged parallel to each other, a bar having its ends pivoted to the adjacent ends 0" the said links, a socket secured on the said bar,
